Nearly 10% of Americans have a nutritional deficiency. Many nutrients are important for good overall health. Most of them, the body gets from certain foods. An official website of the United States government The.

Population database on dietary intake, identify the current prevalence of nutritional deficiencies of key micronutrients critical to immune function, review the function of these deficient nutrients important to the immune system, and discuss strategies to fill dietary nutrient gaps.
While many essential nutrients are important for immune health, we have chosen to focus this manuscript on vitamins A, C, D and E because of the significant nutritional deficiencies we found in the U.S. The population, as well as zinc, which was the greatest deficit of minerals related to the immune system. Our research shows that foods plus a dietary supplement had a lower prevalence of nutrient deficiencies than foods alone. The percentage of the population with a usual intake lower than the EAR in adults (≥ 19 years old) from food alone versus.
Food and dietary supplements for vitamin A (45 to 35%), vitamin C (46 to 33%), vitamin D (95 to 65%), vitamin E (84 to 60%) and zinc (15 to 11%) (figure.

A nutrient deficiency occurs when we don't get adequate amounts of the six basic nutrients we need to stay healthy. And as I always like to reiterate, our body needs a balanced amount of these nutrients (water, protein, carbohydrates, fats, vitamins and minerals) to stay healthy. Micronutrient deficiencies are a major global health problem. It is estimated that more than 2 billion people in the world today are deficient in key vitamins and minerals, in particular vitamin A, iodine, iron and zinc.
Most of these people live in low-income countries and are usually deficient in more than one micronutrient. Deficiencies occur when people don't have access to micronutrient-rich foods, such as fruits, vegetables, animal products and fortified foods, usually because they are too expensive to buy or are not available locally. Micronutrient deficiencies increase the overall risk of infectious diseases and of dying from diarrhea, measles, malaria and pneumonia. These conditions are among the top 10 causes of disease in the world today.
The National Health and Nutrition Examination Survey (NHANES) is a biannual cross-sectional study of the U.S. population conducted by the Centers for Disease Prevention and Control (CDC). Like other dietary reference intakes (DRI), EARs are determined by panels of experts appointed by the Food and Nutrition Board of the National Academy of Medicine (formerly the Institute of Medicine). The pH professional healthcare team includes recognized experts from a variety of disciplines related to health care and other related disciplines, including doctors, lawyers, nutritionists, nurses, and certified fitness instructors.
Fortification is the addition of nutrients to replace losses that can occur in food processing, and fortification is the addition of nutrients to food to prevent or correct a nutritional deficiency. Nutritional evaluations in populations are generally performed by measuring nutrient intake through dietary surveys and comparing average intake with specific nutrient needs by age and gender. To avoid the bias associated with self-reporting dietary intake, nutritional biomarkers can be used to assess food exposure and nutrient intake. Blood levels of magnesium are strictly regulated and cannot be used to assess the nutritional status of magnesium (4).
In addition to the collection of dietary data, some NHANES data include biochemical evaluations that function as objective indicators of dietary intake and report on the nutritional status of participants). The information should not be used in place of consultation with a competent health or nutrition professional. Therefore, dietary surveys and nutritional biomarkers are two methods used to assess the food exposure of a population. While it is more difficult and costly to do so in entire populations, sometimes nutritional biomarkers are also used, biochemical indicators that provide more objective and reliable measures of dietary exposure and body nutritional status (6,.

A very low dietary intake of a nutritionally essential vitamin or mineral can lead to a deficiency disease, called micronutrient deficiency. In fact, the National Health and Nutrition Examination Surveys (NHANES), which assess the nutritional and health status of a nationally representative sample of the civilian and non-institutionalized U.S. population, have reported a high prevalence of select micronutrient deficiencies in the U.S.
population (see tables 1-. The goal of the pH Labs team is to educate and help people avoid diseases by being proactive to avoid nutritional deficiencies. Many Americans are exceeding their energy needs (calories), but are not meeting their requirements for micronutrients (nutritionally essential vitamins and minerals). .
